What Our Customers Say
EXCELLENT Based on 73 reviews Posted on XianTrustindex verifies that the original source of the review is Google. Paul was super professional and easy to deal with. Highly recommendPosted on Matteo “Lilxe” ITrustindex verifies that the original source of the review is Google. Paul did an excellent job running two Cat 6 cables through our roof and setting up a reliable solution for our home network. He recommended a WAP system with a PoE switch, which completely resolved our coverage issues. Professional, knowledgeable, and efficient. Highly recommend his services.Posted on Tony McLeanTrustindex verifies that the original source of the review is Google. Had a great experience with Paul on nbn recableing, great bloke very experienced and knowledgeable, excellent work level and he even set up the modem while he was there. Not many go that extra mile. Thanks again PaulPosted on Luca CarusiTrustindex verifies that the original source of the review is Google. Paul from ARCS was an absolute pleasure to deal with. We were able to book him in very quickly, he listened to exactly what we wanted, and his workmanship was excellent. It really felt like he treated our home as if it were his own. The job took over two days due to the scope, but Paul was easy to contact, flexible with our availability, and very accommodating throughout. Pricing was fair and transparent, and the end result was spot on. I’ll definitely be using ARCS again for any future cabling work and wouldn’t hesitate to recommend him.Posted on Claire HutchinsonTrustindex verifies that the original source of the review is Google. I contacted ARCS to get help with FTTN drop outs after countless NBN Co appointments that went no where. I knew I was in good hands straight away with Paul. Not only did he fix problems that NBN co should have fixed but he spent the time to check all possible solutions and ensure we’d have no future issues. It’s so good to know you can still get friendly, reliable and honest service. Wish I called sooner! Thank you so much, Paul.Posted on Ed NeevesTrustindex verifies that the original source of the review is Google. I read a load of reviews about the team at ARCS and was really pleased to hear about people’s experiences. Not only that but they were relatively local to me too! The experience completely lived up to my expectations, with the feeling of a family member helping you out, the quality of installation that feeds my OCD and a professionalism that is top notch. Went from a 3 node mesh wifi that would constantly drop for no reason to a 2 Access Point system with hard wired TV’s that is pretty much maximum speed that our plan allows. Really looking forward to never thinking about my WIFI again!!! If you want the same I can’t recommend ARCS enough.Posted on Eddie RijkTrustindex verifies that the original source of the review is Google. We were having ongoing issues with our internet service at home. Telstra were no help & said there wasn’t any fault at their end. We contacted Paul & he came very quickly. He tested everything and proved that the fault was caused at Telstra’s end. Paul explained everything to us & even made a video clip explaining the problems, so we can show the Telstra tech when they finally turn up. If you are having technical issues, I highly recommend Paul. Thanks for your help Paul. I would have given you more than 5 stars if I could😀Posted on Kent “Doug” DouglasTrustindex verifies that the original source of the review is Google. Paul at ARCS came to inspect the "stage 1" work of NBN connecting fibre to premises and found multiple issues with the installation. He was able to confirm the existing premise wiring was not compliant with the "stage 2" FTTP installation. I engaged him to lay a new fibre connection to the house in order to make the future NBN work a seamless transition and he exceeded expectations. He was able to do the work utilising existing infrastructure without any new holes or damage and then tidied up the woeful work the NBN contractprs had performed when installing the new lead in fibre. He also managed to repair the existing connection NBN damaged as we had been without internet for nearly a week. I could not recommend him highly enough and will certainly utilise his skill for any future cabling projects.Posted on PeterpetrumTrustindex verifies that the original source of the review is Google. We highly recommend Paul from ARCS. We were having problems with our internet connection with Vodafone. Vodafone said that it was all OK as far as the NBN node, but the problem was with the wiring from there to the house. We found Paul and he arrived when arranged and within minutes had identified two issues. One he fixed immediately, with an instant increase in speed, the other was in a junction box on the Telstra line that was inaccessible. He checked and found that NBN fibre would soon be available in our area and provided all the information we needed to arrange for NBN to link us up. Paul is affable, friendly and obviously very experienced. If you live in the Penrith/Blue Mountains area, he is the person to go to.
